OHARLEs H. SHAW, OF BROOKLYN, ASSIGNOR F ONE-HALF TO JOHN H. V

REYNOLDS, OF TROY, NEW YORK.

STOPPER FOR THE FEEDlNG-HQLES OF CANS.

SPECIFICATION forming part of Letters Application filed September 6,1881.

To all whom it may concern:

Be it known that I, CHARLES H. SHAW, of Brooklyn, in the county ofKings, and State of New York, have invented certain new and usefulImprovements in Stoppers for Feeding- Holes ot' Cans, &c., of which thefollowing is a specification.

My invention relates to improvementsin stoppers for the feeding-holes ofcans, but es- 1' a pecially forthe class of cans that is designed forvolatile oils and other similar liquids; and the Object of my inventionis to provide a simple and reliable means for perfectly closing thefeeding-openings of such vessels without having recourse to the usualmode of closing them by means of a patch of metal soldered thereon,which latter mode, by reason of the heat required for soldering, isfraught with greatdanger when the can contains volatile 2oandinflammableliquids. This object I attain by means of the devicesillustrated in the accompanying drawings, which form part of thisspecification, and in which- Figure 1 is a plan View of a portion of acan containing my improved stopper in a closed position; Fig. 2, a likeview with the feedinghole open; Fig. 3, a vertical section of Fig. l atthe line mm; Fig. 4, a reduced plan view of a can containing my improvedstopper; Fig.5,

0 an inverted plan view of a modification of my invention, and Fig. 6 avertical section of Fig. 5.

As represented in the drawings, A is the top of a square can of the kindcommonly 5 used for holding volatile oils. The sides of the can, byprojecting above the top A, form the standing rim (1, wherebythe stopperis protected from displacement and injury. I B is the feeding-hole,'madein the top A, and

0 preferably located near one corner of said top for the purpose offacilitating the emptying of the can. 0 is a swinging under cover forthe feeding-hole. It is pivoted to the under side of the top A by meansof the rivet c, and is provided with a check-arm, c, which engagesagainstthe side of the can, as shown by the dotted lines in Fig. 2, andprevents said under cover from being pushed out of reach from theexterior of the can. The under cover, O,is also provided witha boss, 0that is tapped for receiving the binding-screw of the cap.

D is the cap of the stopper, provided with a binding-screw, d, fitted toengage in the tapped hole in the boss 0 of the under cover.

Said binding-screw may be made a separatev piece, as shown in Fig. 3, orit may be an integral part of the cap, as shown in Fig. 6. A gasket orpacking, E, of leather, paper, or

other suitable material, is placed beneath the cap D for the purpose ofproducing a hermetic joint between said capand the top of the can.

The operation of my invention is as follows: To fill the can the cap Dshould be removed by releasing the binding-screw d and the under cover,(1, swung back, as shown in Fig. 2, so as to permit of the introductionof a funnel into the feeding-hole B, and then the liquid is pouredthrough the funnel into the can. The can is stopped by swinging theunder cover, 0, over the feeding-hole B and screwing down the cap D bymeans of the binding-screw.

For pouring the liquid out of the can, the cap D may be removed, asabove described, or the binding-screw may be turned back far enough tofree the cap D from the top, and then the cap and under cover will swingas one piece until the screw (1 strikes the side of the feeding-hole,and thereby the latter will he opened sufficiently to permit the contents of the can to be poured out.

In the modification shown in Figs. 5 and 6 the cap D, provided with thebinding-screw d, and the gasket E are the same as those previouslydescribed herein. A flange-piece, F, is hermetically secured to the topof the can, and is provided with a hanging bridge, f, the crosspiece ofwhich hasa boss, f,tapped to receive the binding-screw d of the cap.-Vhenthe cap D of this modification is removed a funnel can be insertedin the feeding-hole B by allowingthe spout of the funnel to pass overthe bossf of the hanging bridge, and the filling of the can effectedtherethrough. In closing the can the cap D is screwed down until thepacking E forms a hermetic joint with the flange F.

. I claim as my invention The combination, with the swinging undercover, 0, pivoted to the top of the can, as herein described, of the capD, provided with a binding-screw, d, and adapted to attach to thethreads of the under cover, (3, substantially as and for the purposeherein specified.
